The vehicle, driven by a man in his 30s, was heading north on San Jose Avenue when it struck Arana, who hit the front windshield of the car and landed in the street, police spokesman Officer Albie Esparza said.

Arana, a San Francisco resident, was taken to San Francisco General Hospital where he was pronounced dead.

The driver, who was distraught, remained at the scene and cooperated with investigators, Esparza said. Drugs and alcohol are not believed to be factors in the collision, he said.
